What is a primary characteristic of secondary intention wound healing?

Secondary intention wound healing is characterized by the process through which larger wounds, such as those caused by trauma or surgical procedures, heal more slowly compared to primary intention healing. In secondary intention healing, the wound is left open and heals from the bottom up and from the edges inward, which takes more time as granulation tissue forms to fill the wound. This method is typically used when the edges of the wound cannot be easily brought together. As the tissue fills in, the healing process can be prolonged, resulting in a larger wound area that takes longer to close. Additionally, secondary intention often results in more noticeable scarring due to the more extensive tissue repair required.
